After reading this article courtesy of CoolSmartPhone.com I decided to give vTap a go.
Its a great little application that has the ability to search wikipedia and better still search video clips from popular sites like YouTube. Once you’ve found the clip your looking for the program will even stream and play it.
You can install it over the air if you simply navigate to http://vtap.com from your Windows Mobile device or even your iPhone.
My only dislike about the application is it adds its own shortcut to my already busy home screen and as yet I haven’t found an option to disable this.
You will obviously need either a Wi-Fi connection or 3G access to be able to stream video to your device.
It comes pretty high on my recommended Windows Mobile software so check it out.
EDIT: Apologies I mistyped the vTap URL for over the air installation. Thanks to akg for pointing this out.
